There are cars driving around Miami in worse shape than that... but they all pass the emission test!

 

Although in this particular case Don the vehicle that the OP is looking at certainly shouldn't be repaired, that's not to say it couldn't be repaired by a competent collision repair facility. Body shops do major structural damage repair every day on unibody cars. These days, that's their bread-and-butter work. I'm not aware of any state laws that would prohibit a vehicle owner from repairing that HHR - if he/she wanted to. (It's still going to have a 'salvage' title, though). Of course, if your state has a safety inspection standard, you might think twice about fixing that one.
